Abstract:
OBJECTIVE To explore the value of bronchoalveolar lavage fluid(BALF)metagenomic next generation sequencing(mNGS)technique in diagnosis of the pulmonary cryptococcosis patients with different clinical features so as to raise the clinicians' awareness of the diagnosis of pulmonary cryptococcosis with BALF-mNGS.METHODS Totally 73 patients with pulmonary cryptococcosis and 73 non-pulmonary cryptococcosis patients who were treated in Wenzhou People's Hospital from Jan.2021 to May 2024 were recruited as the research subjects.The clinical data including baseline data,complications,clinical manifestations,clinical laboratory test data,ima-ging findings and serological test data were collected from the patients.The sensitivity and specificity of BALF-mNGS in diagnosis of the pulmonary cryptococcosis were observed,and the difference in the sensitivity in diagno-sis of the patients with various clinical features was analyzed.RESULTS A total of 73 patients with pulmonary cryp-tococcosis were enrolled in the study,44 of whom were male,and 29 were female;62 were positive for BALF-mNGS,11 were negative;all of the 73 non-pulmonary cryptococcosis patients were tested negative for BALF-mNGS,the sensi-tivity of the BALF-mNGS test was 84.93％,with the specificity 100.00％,the positive predictive value 100.00％,the negative predictive value 86.95％.Totally 45 patients had the symptoms of cough and expectoration,42 of whom were positive for BALF-mNGS,the test sensitivity of the patients with the symptoms of cough and expectoration was 93.33％,higher than that of the patients without the symptoms of cough and expectoration(P＜0.05).Totally 31 pa-tients had the lesion site of right lung,30 of whom were positive for BALF-mNGS,and the test sensitivity of the patients with lesion site of right lung was 96.77％,higher than that of the patients with the lesion site of left lung or both lungs(P＜0.05).Totally 44 patients had multiple lesions,41 of whom were positive for BALF-mNGS,the test sensitivity of the patients with multiple lesions was 93.18％,higher than that of the patients with single lesion(P＜0.05).CONCLUSIONS The sensitivity of the BALF-mNGS is high in diagnosis of the patients with pulmonary cryptococ-cosis,especially for the patients with symptoms of cough and expectoration,lesion site of right lung and multiple lesions.It can be used for the early diagnosis of pulmonary cryptococcosis.
